The present invention has relation to pipe organs and consists ofimproved means for effecting the operation and the control of the stopsof the organ. Heretoi'ore the stop keys 5 are usually separately andselectively operated to place the stops in both the on and ofi'positions and in some instances means have been previously proposedwhereby the stops are separately and selectively brought into lo the onposition and then collectively returned to the oli position.

According to the present invention, the stops are separately broughtinto the on position by selective operation of the respective stop keyand then all the stops set in the on position, are thrown back to theofi' position by a single operation or touch of anyone of the stop keys.All the stops are so arranged and associated with each other that uponinitial or first touch oi a stop key the stop associated therewith isbrought into the on position. Any number of stops can be brought intothe on position and in which position they will remain until any one ofthe stop keys is operated or brought to a point beyond the position itis in after the first or initial operation. The operation of these stopkeys may be termed a double touch action, that is, on the first touch ofthe key the stop is brought into the on position and then a double oradvanced touch of any one of the keys, whether or not this key is in theon position, will elect operation of a control device which will causeoperation of the actuating means for the various stops. Each stop hasits own actuating mechanism comprising an on and an oilE magnet operatedthrough a suitable electric circuit and each magnet in turn eiiectsoperation of pneumatic actu* ators which are arranged to open ports toad.- mit compressed air to effect operation of the mechanism whichcauses the stops to open or close to bring the same respectively intothe on or off positions.

55 The mechanism or means for actuating the individual stops is of anysuitable kind and there is such a mechanism for each stop. According tothe present invention a common control device is provided and designedso that this single control device will operate to 1930. Serial N'o.461,373.

control one or more stops. This device and the means comprising thedouble touch a"- tion associated with the stop keys form essential partsot' the present invention. The improved device and means include theusual stop keys, each being connected with a spring actuated cleaver.Each stop key carries a movable contactor which is brought into contactwith a lined contacter when the double or advanced touch is given to thekey. This latter contacter completes the electric circuit which eiiectsoperation of the olil magnet to throw the on stops into the ofirqposition. In the first touch et the stop key the contact is not made asabove stated; therefore said electric circuit is not completed but inthis first touch, either by electrical or mechanical means, the selectedstop is brought into the on position. Y

An embodiment of the invention will be described hereinafter withreference to the accompanying drawings; whercin- Figure l is a sectionalview showing the individual stop actuating mechanism together with thecontrol mechanism and the stop actuating means7 the latter being showndiagrammatically; and

Figure 2 is a diagram showing the arrangement of the different apparatusor means employed and also the arrangement of the electric circuits.

The salient feature of the present invention is the double touch meansor mechanism employed for actuating individual stops and the commonassociated control device or mechanism forms another part of theinvention. Any well known means 'for operating' the stops may heempiovcdv and therefore such means are only illustrated diagrammatnically in the accompanying drawings.

Referring to the aforesaid drawings the means 'for actuating theindividual stops are similar in constructon and arrangement and it willbe understood that one of such devices is employed for each stop. Saidactuating means comprises the key l which is carried bythe Cleaver 2pivotally suspended from a part of the organ key-board framework 3. Themeans for suspending this Cleaver includes ya hanger 4 land said cleaveris con- `ina-cnet land 61.1@

nected thereto so as to pivot on the pin 5. A spring 6 is employed toreturn the key and clearer to the normal or ott" position when theoperation tor rcturninothe said key to the oli position has beenperformed, The spring tension which controls said key and Cleaver isadjusted vby -n'ieans ot screw 7 engaged within a threaded hole in apart ot the keyboard framework of the organ.

The key 1 en the underside thereotcarries an insulated resilient pad Svand which pad lies over a i.\;ed contacter 9. The key 1 carries themovable contacter 10 which is insulated trom said fixed contacter 9 bymeans of the insulating; pad S. The key-board frame a. iixed contact 11which is electri- 4ally connected to the 'feed or source ot electriccurrent by conductor 12. The concluetor 13 connects the contacter 9 withthe 'magnet 141 ot' the control device 15. The latter device consists ofa casingl 16 enclosing the magnet 14 and which casing is sub-divided toprovide air chamber 17 and air passage 18. 'lhe control device comprisesas other Working parts, besides the magnet7 a movable block 19 Whichcarries the movable contactors 2 0. The said block v19 is raised bymeans ot the pneumatic actuator device 22 which is inflated by air so asto lift said block 19 to bring the movable contaetors 2O into contactwith the fixed contactors 21 which latter contact completes the circuitthrough conductor 23 to the off magnet or magnets 241. The lattermagnets are located in the diagrammatic illustration -ot the operatingmeans 25. As previously explainedthis operatingjr means or mechanismWill be provided with as many on and ott magnets as required tocorrespond with the number ot stops of the organ. As previouslyexplained7 the on and ott' magnets are operated in the usual Way by theordinary operation/ot the respect-ive key 1 which in said operation isnot brought to a position beyond that shown in Figure l1 wherein thecontaotors 9 and 10 Vare not vin contact.

In the voperation of the improved Vmeans or device, a stop key 1 isinitially operated by the tiret touch in a manner common to practice,that is, pressure on the key will operate the pi voted cleaver 2 which,through the medium oi? connecting link 26 operates lever 27 and thelat-ter in turn operates a suitable device tor mechanically effectingthe operation ot the means tor placing the stops in the on and ettpositions. This means operates in the usual Way common to other-organstop actuating mechanisms to vopen the respective port to admitcompressed air.

ln common practice when electrical means are employed the on magnet isretained in the operative position until means are brought into actionto cle-energize .said von e the @ft magnet to throw `mal or o position.WithA c the stop te itv free-aes the present invention, `the action ofreturning the stops to their normal or closed position is greatlysimplified and therewith any combination of stops may be readily broughtinto action by the first or initial touch of the respective keys. To getvarious combinations the stop keys may be operated together orseparately with the double touch and if the key or keys are held in theoperlated position, the respective `magnets Will'lremainin the onposition, but other stop keys then in the on position will be returnedto the eti position.

position and upon operation -ot any one of the keys with increasedpressure or, as herenibelfore termed, a double touch, themova'blecontacter 10 carried by the 'operated key 1 is brought into conta-ct`with the lined contaeter 9 by compression ot the insulating pad 8 whichispreterably composed otsott elastic material such, ter example, as atelt pad. TWhen the contactor-Q contacts With contacter 10, the circuitthrough conductor 13 is established and the magnet llQ vthe vcontroldevice 1a-is actuated to niove the val-ve stem 2.8. This valve stem l.rarr-es the valves 29 and 30. The valve 30 opens the/port between thechamber 17andthe air passage `18 and Awhen said valve 30 open valve 29lcloses the outlet port-lcf-the aforesaid passage 1S- VVhen air isadmittedfthrough .passage 18the pneumatic actuator is inflated to, raisethe block 19 caithe Vcontaeters 20. Centact is made Withthecontactorplate 2 2 and through this contact Velectric .circuits are establishedvto operate all theolimagnets Vcollectively so as to close all the openstops by the double touch operation ot any one ofthe stop keys, aspreviouslydeclined.

The essential feature yof 'the invention her-einbetore described is theso tern'ied double touch mechanism usedeither alone Aor conjuncti-velywith a. control device electrically .connected therewith. Both ot saidmeans or devices may be used separatelyor together with various knownmeans :for mechanically or electrically operating` the stops of an organA'and it is to be understood that any modiiication, either in 'theconstruction or application ofthe invention here-inbe'forc describedcoming fairly Within the terms of the appended claims shall be coveredthereby.
